Reaktionsschritte

A mixture of 3-(4-chloro-2-phenylamino-pyrimidin-5-yl)-2-(4-methoxy-phenyl)-propionic acid methyl ester (45 mg, 0.11 mmol) (from Example 12a supra) and cyclopropylmethylamine (1.0 mL) (Lancaster) was stirred at room temperature for 24 hours. The reaction mixture was then diluted with ethyl acetate (50 mL) and successively washed with water (10 mL) and brine (10 mL), dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give the crude 3-(2-phenylamino-4-cyclopropylmethylamino-pyrimidin-5-yl)-2-(4-methoxy-phenyl)-propionic acid methyl ester which was used in the next step without further purification. (Yield 51.3 mg).
